Where could they inject me for the chemo?

In veins: Most chemo is delivered systemically. There has to be constant access to veins. When veins of the hands or arms are employed they eventually thrombose and cant be used. Other access sites are employed such as a pic line where the catheter is passed up a vein in the arm and fixed in place for easy access. Otherwise a subclavian port is positioned with the reservoir on the chest wall for access.
